webMethods Integration Server is one of the core application servers in the webMethods Fabric platform. It is a Java based, multiplatform enterprise Integration engine supporting the execution of services to perform the integration logic such as data mapping and communication with other systems. The Integration Server supports Java, C/C++ programming languages for writing services as well as a proprietary graphical language known as flow. It also supports graphical configuration of 3rd party system operations via the concept of "Adapter services".[1][2] One of the big selling points of the Integration Server was the graphical form of coding using flow to perform mapping and other common integration/B2B tasks that are tedious in conventional, text based languages. This allows rapid development and intuitive creation of mapping logic (a large part of a typical enterprise integration project). The Integration Server exposes its administration, configuration and auditing facilities to the user via an HTML web interface.
